`This isa division of my application Serial )la-342,367, tiled onf February 25, 1929. i

IThis Iinvention rela-tes to platens for printing and-addressing machines-and has for its object'generallyY to provide a novelzand simplesectional plat'enffor repetitions printing ofall or a certain part of aprinting form, or for alternate printing of parts of the form.

` The invention isapplicable, for exam-ple, to zin-addressing machine fory making impressions from printing devices which -are run through the machine one ata time. "A- sim-ple embodimentof these printing devices com-k prisesa'form for printing a name and a city and'fstate-address in two lines, one above the other. Many of` these printing devices are provided with forms forstreetaddresses, or for a variety ofother information, butthe simpleform will be suiiicient to illustrate the use ofthe invention. 'It may be desired" to print Aonly'the name or only the address vof all such simple printing devices, or it may be desired to print the name and addressend to end on the same-line for listing or other purposes. I have found that this can be easily accomplished and produce entirely satisfactory printing impressions by providing a sectional platen adapted to have one or the other, or both sections, set for repetitions printing, or to have the sections set for alternative printing.

Another object of the invention is to provide a device of the above described character in which the cushion plates of the platen may be attached to the platen blocks in a simple and economical manner.

The invention can be embodied with a reciprocating platen or stamping arm of the character disclosed in Patent No. 1,681,525, patented August 21, 1928, or it can be embodied with a spring or snapping platen and with a reciprocating or iXed platen, or with a stamper arm of the type disclosed in the application of Henry E. Hubbard, Serial No. 341,935, liled February-23, 1929, but I have chosen to illustrate it with a iXed platen -or stamper arm as a selected embodiment of the invention and, referring to the accompanying drawing,

Referring .to the drawing, `4 is; affixed platen .or stampen arm .of :an c addressing machine. inwhich printing devices are fe'd, :one

the Well Vunderstood practice. :The-platen comprises .a skeleton head L8 secured-onf the I support by a holding screw bolt 9and maintained in proper position by adjusting screws 10, 1Q. Thereare two platenI-blockslland 12 movably arranged -sideby'rside on the platenlihead, and thesebloeks are provided at their-ends.with-camfsurfaces 11 and12. .The blocks are yieldably held in the |hea'd by springs 13 that' havev oppositefends attached toi'pins on' the'headand pins onthe block. A shaft 14fis rotatably and longitudinally movable in theplaten headan'd' hasxcams, suchaas 15,1 arranged. thereon whichf engage -thef camisurfaces 16 and 17,: and-a-shif-ter 16: :is: rigid .ont the shaft andr may? be. integral with ,the-i camV 15, as shown, and this-'shifter carries two rollersland 17. A tripper18 isgpivotedat 18 onthe platen. arm14-and carriles ai .pin-.'19 whichjprojects through 1an arcuate-slot 2O in the arm and carries awasherz21 whichoverlapstheslct. spring22 iszattachedfat fone. endiftothe pin 19 and at its'other end toi a -pin122 on' the armi/1 at the raghtfofzthegpin 19, Fig. 1. fAIspring' 23Yis attached atzone.

The trigger hangs freelyfrom itszpivot 18', but is held normally inficenterediposition by the springs 22l and' its? .bottom :'withff a foot 24 and a recess 25. By adjusting the shaft longitudinally the shifter Will be moved into operative rela-tion with the tripper for alternative printing orout ofirelation With the tripper forrepetitions printing. Each of the blocks ll and 12 is provided with a longitudinal recess 26 to receive aremovable plate. 27 having a cushion facing 28. These plates are detachable so that they can be' replacedV engage keyhole slots 3l in the plates 27.V

The heads 30 are adapted to enter the keyholeslots when theplatesare arranged to 'enter the longitudinal recesses 26 in the platen blocks. The heads and the Walls of the keyhole slots are beveled to effect interlocking engagement ofthe heads with the plates whenV the plates are moved lengthwise relative to the platen blocks in order that the plateswill be snugly held in place on the blocks. The plates-are provided .With handles 27 to facilitate attachment with and detachment from the blocks. The shifter has an arm 82 Which carries a detent 33 that is adapted to engage in a recess 34 in the end of the block 11, a recess 35 in the Vend of the platen block 12, or a recess 36 partly formed in the platen block l1 andpartly'formed in the platen block 12 to lock the shifter in position When the shaft and shifter are adjusted for Vcausing either or both of the platens to operate. By employing this latter arrangement and properly positioning the detent in one of the openings leither or both of the platen blocks may be v*moved downwardly into printing position. Y Y

The particular feature of my invention, as disclosed herein, relates to the expeditious manner in Which the plates 27 may be secured to or detached Afrom the platenV blocks and, manifestly, this arrangement is 'such that these plates may be readily operated foi` either of the above arrangements. Y

l have shown the invention in asimple embodiment but, as indicated before, the invention is capable of embodiment in machines having reciprocating platen arms and in machines having spring or snapping platens, as Well as in addressing and printing machines of many kinds, and it is to be understood that the facile manner of cushion pad carrying plate, installation or removal, may be used in connection with other types of platens or platen blocks and I reserve the right to make Yany changes in the invention that may be necessary ori desirable Within the scope of the following claims:

'I claim:

l. A platen for printing and addressing machines comprising a block, a cushion plate having a slot in the backthereof, .and yieldf ing'means on the face joffthe block'for engaging said slot to detachably mount the cushion plate on the block.

2. A platen for printing and addressing machines comprising a block, a cushion plate having a keyhole slot, and yielding means on the block for engaging said 'keyhole slot to detachably mount the cushion plate on the block.

back thereof, said plate and head portions including cooperating sections for insuring engagement of said head portions in said slots to interlock said platen and plate.

5. The combination with a platen, of a cushion plate, and yieldable'retaining means on the face of said platen, said cushion plate including portions Von the back thereof.l for cooperation with the retaining means for con-r necting said cushion plate to said platen.

6. The combination with a platen having a recess, of -arcushion plate having a part extendable into said recess, retaining means on said platen ,including spring-pressed retainers extending into said'recess, said `plate having slots in the face of the partthereof extendable into said recess whereby heads on said retainers may be introduced-'into said slots to connect said plate to said platen;
